Lightning on Jupiter could be up to 1 million times stronger than on Earth

"Could the key difference be hydrogen versus nitrogen atmospheres, or could it be that the storms are taller on Jupiter and so there's greater distances involved?

Based on missions that could only detect the most powerful dark-side flashes, previous research had suggested that Jupiter's lightning was similar to the highest‐energy lightning flashes on Earth, known as "superbolts. " However, when NASA's Juno spacecraft began orbiting the giant planet in 2016, its star-tracking camera was sensitive enough to detect what appeared to be numerous weaker, Earth-like flashes.

In the new study, Wong and his colleagues instead analyzed data from Juno's core instrument, which could detect radio emissions from Jupiter's lightning. Such data could yield a more precise way to measure lightning power unaffected by obscuring clouds.
